I saw a video where a company was doing molds and their flask was about the same perimeter dimensions as yours but about double the height.

I ...Hi omnombluist, Thank you for you kind comment. I agree that there isn&#39;t too many sites that go into the depth regarding metal casting. I am very satisfied with my refractory. I used my new furnace for over 50 melts and about 2 hours each session. I use propane burner (no air blower) and the aluminum melts in 25-35 min every time. The refractory is a bit fragile and there are crumbling and cracks especially on the lid part. Good solution for fixing those cracks is too use Fire cement (ready mix). It comes in a tube same as the silicone tube and you can fill all the gaps and loose cement areas. After using the foundry the fire cement filler will dry and harden. <br />If I would replace the refractory in my furnace I would probably weld another inner cylinder for the foundry and pack one layer of ceramic wool for insulation and another inner cylinder section of fire cement mixed with Portland cement. If you use only Portland cement it will crack very fast probably after the first use of the foundry. Good way to check if you foundry is heat officiant is placing you hand on the outside of the foundry after about two hours of use. If it feels worm that means its well insulated and if its boiling hot that means it not insulated properly and the foundry is loosing heat.<br />Thanks again for your comment ;-)<br />Regards AharonAharon's blogshttps://www.blogger.com/profile/05711316858800111186noreply@blogger.comtag:blogger.com,1999:blog-5434634429369908904.post-23998998588492170152011-09-14T03:23:29.184-07:002011-09-14T03:23:29.184-07:00Great creativity and I really like this and I also...Great creativity and I really like this and I also appreciate your creativity.

First, you are doing great work and...Hello Aharon, <br />First, you are doing great work and I appreciate how detailed your documentation is. Good documentation is terribly lacking in our hobby. <br />Second, I am curious how well your refractory is holding up. Mine was only made of portland cement so I expected it to crumble after some use but I am looking for good long term replacements. Would you recommend fire cement or have you found a better alternative? <br />Keep up the great work! Lost arts need to be found again!Omnombulisthttps://www.blogger.com/profile/03795395747873894438noreply@blogger.com
